| uncommon campylobacter species in infant macaca nemestrina monkeys housed in a nursery. | studies were conducted to characterize 18 isolates of campylobacter spp. that could not be identified as either campylobacter jejuni or c. coli. the isolates were cultured from specimens from 13 of 18 infant nonhuman primates during a prospective epidemiologic study reported previously. phenotypic tests, dna hybridization, and analysis of dna coding for rrna identified the isolates as c. butzleri (seven isolates), c. hyointestinalis (seven isolates), and c. fetus subsp. fetus or c. fetus subsp. ... | 1992 | 1452677 |
| clinical and parasitologic aspects of cryptosporidiosis in nonhuman primates. | eighty-one cases of acute cryptosporidiosis were diagnosed among 157 (52%) infant primates, predominantly macaca nemestrina, housed in the nursery unit of the washington regional primate research center. the mean age at onset of oocyst passage was 38 +/- 25 days. the outbreak was confined to the nursery and no cases were detected among juvenile or adult primates housed in other rooms within the colony. all but one animal manifested symptoms of enteric infection, including severe diarrhea and deh ... | 1990 | 2153858 |
| evidence of reinfection with multiple strains of campylobacter jejuni and campylobacter coli in macaca nemestrina housed under hyperendemic conditions. | a prospective bacteriologic study of 18 infant pig-tailed macaques (macaca nemestrina) housed in a nursery facility in which campylobacter spp. are endemic was undertaken to determine the epidemiology of infection and reinfection. the isolates of campylobacter jejuni and c. coli cultured from 8 of the 18 infants were characterized by serotyping, dna hybridization, and polyacrylamide gel electrophoresis protein profiles. the chronology of infection was indicative of multiple reinfections with dif ... | 1990 | 2365455 |
| experimental campylobacter jejuni infection in macaca nemestrina. | experimental infection of four specific-pathogen-free macaca nemestrina monkeys (aged 3.5 and 4.5 months) with campylobacter jejuni 81-176 caused acute diarrheal illness, characterized by fluid diarrhea, bloody stools, and fecal leukocytes, which lasted for approximately 7 to 11 days. histologic examination of intestinal biopsies showed acute colitis characterized by infiltration of the mucosa with neutrophils and lymphocytes, and cryptitis. there were no histologic changes in the small intestin ... | 1989 | 2707853 |
| prevalence of campylobacter in infant, juvenile and adult laboratory primates. | a cross-sectional study of campylobacter spp. infection was conducted on 125 infant (macaca nemestrina and macaca fascicularis) in an infant primate nursery housing infants from birth to 18 months of age, and 145 m. nemestrina aged from 4 months to 15 years at another facility (primate field station) housing animals from birth to aged adults. the objective was to determine the prevalence of campylobacter spp. in various age groups and to investigate the correlation with diarrhea. in the infant p ... | 1988 | 3265462 |
| identification of campylobacter jejuni in macaca fascicularis imported from indonesia. | campylobacter jejuni was selectively cultured in 33 (66%) of 50 macaca fascicularis that had been imported from indonesia. as there was no published information on the incidence of campylobacter infection in nonhuman primates from indonesia, a survey was conducted to determine the presence and incidence of campylobacter jejuni in 50 macaques before they were exported from indonesia. the organism was positively identified in 18 (36%) of the specimens examined. repeat cultures after importation an ... | 1983 | 6855191 |
